From a "cheap" line of blades, MTech has a 3" blade neck knife that's well worth the $12.00 admission price. It is called the MX-8038 it is a Tanto type blade (black, of course) that has G10 scales and a 3.5" grip. They are claiming that it is made with 440C steel, but I'll bet that it is really 9Cr18MoV steel.

Youtube videos extoll its virtues, a great Kydex sheath, and good edge=holding capabilities speak well for the inexpensive unit.
Does anyone have any experience with this neck knife?
